API Overview

Dynamsoft Barcode Reader (DBR) SDK is built on the Dynamsoft Capture Vision (DCV) architecture.

Main APIs

Category	Library	Description
Orchestration	DynamsoftCaptureVisionRouter	Core Capture Vision Router APIs for configuring settings, starting or stopping capture, and registering receivers.
Input & UI Enhancement	DynamsoftCameraEnhancer	APIs for camera control, image enhancement, and camera UI.
Functional Modules	DynamsoftBarcodeReader DynamsoftCodeParser	APIs for functional modules, mainly for decoded results and result processing.
Infrastructure & Utility	DynamsoftLicense DynamsoftCore DynamsoftUtility	Licensing, basic structures, intermediate results, and utility APIs.

CaptureVisionRouter

The main class DSCaptureVisionRouter acts as the SDK entry point and provides the following essential APIs:

Configure Settings

API	Description
`initSettingsFromFile`	Load settings from a custom template file.
`DSSimplifiedCaptureVisionSettings`	Access commonly used settings through a `DSSimplifiedCaptureVisionSettings` object.

Start/Stop Capture

API	Description
`startCapturing`	Start processing input frames with the selected template.
`stopCapturing`	Stop the current capture process.

Receive Results

Implement DSCapturedResultReceiver to receive capture results.

API	Description
`onDecodedBarcodesReceived`	Callback for receiving barcode decoding results as a `DSDecodedBarcodesResult` object.
`onParsedResultReceived`	Callback for receiving parsed results as a `DSParsedResult` object.
`onCapturedResultReceived`	Callback for receiving all result types as a `DSCapturedResult` object.

Input - CameraEnhancer

DSCameraEnhancer is a built-in implementation of DSImageSourceAdapter. It combines camera control, image enhancement, and a UI system designed for the Dynamsoft Capture Vision architecture.

Result

Result	Basic Item	Type
`DSDecodedBarcodesResult`	`DSBarcodeResultItem`	`CRIT_BARCODE`
`DSParsedResult`	`DSParsedResultItem`	`CRIT_PARSED_RESULT`
